LDO IP Blocks
LTRIM Technologies introduces the LTR18xx family of low dropout (LDO) voltage regulator IP blocks. The LTR1801-2.4T25, LTR1802-2.5T25, and LTR1803-T25 IP blocks are designed to increase the operating time of battery-operated system-on-chips (SoCs) by offering features such as low dropout voltage, low quiescent current and fast-response low power shutdown modes. All the IP blocks support a wide input voltage range (2.7 to 5.5 V) with good power supply rejection ratio (PSRR) over an extended temperature range. End-user applications enabled by these characteristics include wireless and handheld portable systems such as handheld meters, mobile phones, Bluetooth devices, digital cameras, pagers, PDAs, laptops and GPS systems. With an output voltage accuracy of one percent and low current consumption (16 µA quiescent and 0.6 µA standby), the LTR1801-2.4T25 is appropriate for system control processor units that are always in standby mode monitoring the system and user interface.
